Title: Method of treatment for residual liquid in liquefied natural gas tank
Inventor: YOSHIZUMI FUSAO
IPC: F17C9/02
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To reduce time required for discharging work by supplying methane gas in a liquefied natural gas storage tank, the heavy component of liquefied natural gas is vaporized by methane gas and also the generated gas is diluted by methane gas supplied from the outside and taken out from the liquefied natural gas storage tanks. SOLUTION: A part of methane gas passing BOG compressor 2' is taken out so as to start supply of methane gas toward the inside of a tank. The methane gas passing through BOG compressor 2' stays at a normal temperature and since its pressure is evidently higher than that inside of the tank, when a nozzle 3 is released, the gas is ejected to the inside of the tank. A heavy component remaining on the bottom of the tank is instantly vaporized by methane gas. The gas inside of the tank is diluted by methane gas to which vaporized heavy component is supplied, becomes BOG in which the methane and the weight component are mixed together so as to be filled in the tank. This gas is sent out toward BOG compressor 2 from BOG feeding out system piping 1.
